Possible for a belt or perhaps a scarf depending on which way you hold it.....

Nice sliding clasp in the front over a hinged caged design.

Possibly gold filled - seems like it but no markings. 

2 5/8" x 1 1/8" x 1/2"

The sliding clasp moves nicely and there are 2 interior pins to hold the belt or scarf......

Neat!
